I have cecha01 with ofw to kmeaw cfw setup and I had run Gaia 2.00 with no crash and I have been choosing different game with it then I update to 2.01 and still I have no problem with Gaia at all. Been playing around with different game and no problem. Hope that help jurai.

Make sure your using "UP0001-GAIA01985_00-7679866932773369-GAMEZ.pkg" when your games are located in hdd0\GAMEZ. Also delete old gaia from XMB, then install the new one. It shouldn't erase the games folder. Thats the only answers I can see to your problems.
